TNSR New Release: TNSR 21.03 Now Available

TNSR Release

TNSR software release 21.03 is here, and not a day too soon! Our intent was to release in February, which would have made it 21.02. Unfortunately, Texas came to a screeching halt when (what we unaffectionately refer to as) ‘Snowpocalypse’ hit.

With that being said, we are proud to announce that TNSR version 21.03 is now available. The focus of Release 21.03 is system stability and manageability. To view the improvements that come in version 21.03, read our announcement blog and the release notes.

TNSR Webinar: VPP in Your Home Lab? Yep. Right Now.

VPP in your home lab? Yep. Right Now.

Vector Packet Processing (VPP) from the project enables astounding software packet processing. It represents where the world is heading for many packet processing needs across edge networking, cloud native networking, and 5G infrastructure. Many network engineers are aware of VPP, but really don’t have a fast, easy way to try it out for themselves, just to see what it’s all about. But if they could, who knows what they might do with it? Good news. There is a way to kick the VPP tires!

In this webinar, Audian Paxson from Netgate walks through how this is done while engaging with end users of the technology: Mike Jennings, Voxtelesys; Dan Streufert, ADS-B Exchange; and Jerry Wilson, Region 5 ESC for their insights.

TNSR Application Spotlight: Overcoming IPv4 Address Space Exhaustion



IPv4 - with its 32-bit addressing scheme which supports 4.3 billion devices - has served the world well for decades. But internet growth, personal computers, smartphones and now Internet of Things (IoT) have nearly exhausted that address space. IPv6 - with its 128-bit addressing scheme, supports 340 trillion trillion (2128) addresses - is the answer. If your network is running out of IPv4 address space, TNSR software can help. TNSR removes address space shackles with its large-scale NAT (LSN) solution. No more TCAM limits. All done in software.

LSN, also referred to as Carrier-Grade NAT (CGN), mitigates the problem of IPv4 address exhaustion by enabling end sites to be configured with private IPv6 network addresses and then translated to public IPv4 addresses by NAT devices in the network operator's network. This allows exhausted public address space to be shared by many end sites and devices. It also shifts network address translation from the end customer to the service provider network.

Hardware-based solutions require sizable ternary content-addressable memory (TCAM) to mange address translation at speed. TNSR software enables LSN/CGN for Tier 1/2/3 service providers and large enterprises running large private networks through key software features including:

  • Mapping of Address and Port (MAP)
    MAP is a carrier-grade IPv6 transition mechanism capable of efficiently transporting high volumes of line-rate IPv4 traffic across IPv6 networks. TNSR supports both MAP-T (which uses translation) and MAP-E (which uses encapsulation). TNSR can currently act as a Border Relay (BR) providing service to Customer Edge (CE) clients.

  • Network Address Translation-Traversal (NAT-T)
    TNSR supports the standards-based approach for IPsec encapsulation in User Datagram Protocol (UDP) to ensure that data protected by IPsec can pass through NAT without discarding packets - key for IPsec VPN connections that traverse connections where NAT is present, especially for service providers.

All of the above is performed in software - eliminating dependency upon expensive TCAM-limited appliances.

Open Call for Testing for pfSense Plus 21.02.2 and pfSense CE 2.5.1 Release Candidates

We're happy to announce that release candidates for pfSense Plus 21.02.2 and pfSense CE 2.5.1 are now available for community testing. Please see our blog post for more information.

For existing installs - System > Update and pick “Next Release Candidate”.

For fresh installs, download the installer here.

  • Check to see if that problem may already exist on Redmine

  • Check for an existing thread in the Release Candidate section of our forum, and reply there.

  • If no thread exists, please create a new thread

Reminder before upgrading:

  • Create a backup before you upgrade, or a snapshot if it's a VM

  • DO NOT update packages before upgrading! Either remove all packages or update packages AFTER the upgrade.

  • The upgrade could take anywhere from 10 to 30 minutes. Do not remove power from your firewall while the upgrade is in progress.

  • Monitor the upgrade from the firewall console for the most accurate view of progress

  • Remember, these are candidate snapshots, not a finished product. It could be a bumpy ride. While many fixes have been included, there are still more to come.

Again, thank you for any feedback along the way to help us towards speedy and thoroughly tested releases!

We Would Love Your Feedback


Our customers purchase through different channels, including the Netgate store, our worldwide Partners, and the US Amazon marketplace. Regardless of where you purchased, we'd love to have your review, feedback, and rating directly on Amazon if you are using a Netgate SG-1100, SG-2100, SG-3100SG-5100, or XG-7100 DT. Amazon's retail marketplace is obviously highly-visible, and customer reviews posted there help us spread the word about Netgate appliances and pfSense software - which ultimately helps us continue progressing the open-source project.

Beyond public reviews, we're always open to feedback and suggestions to improve our products and processes. There are many ways to reach out and talk with us!  Our sales team, TAC engineers, product management & marketing team, and customer care engineers are all passionate, knowledgeable and happy to hear from you.
